I hate how these companies have malevolently made it so you don't have any choice about installing what ammounts to sophisticated surveillance devices in your own home.
When I talk about HIPAA protected issues with my family, in my own home, I should not suddenly see ads directly targeting the related condition I was talking about, and yet I do.
In general, there's no reason to network connect your TV, but if you do, and they won't they don't tell you this, you don't have to accept the TOS for the SMART features or data collection. The TV will still work.
Also, providers have implicitly forced you to agree to ToS to use the device by not returning it and bundling a take it or leave it agreement with the TV.
If you want to watch TV, this is your only option. That's not even getting into the mesh networks, or the obvious expansion of those networks to their trucks.
